The purpose of this construction and which may be very readily will be explained later. If desired, a wire cleaned. or rod 31 may be disposed between the front 20 These and other objects are attained by edges of the walls 11 and 14 in order to give the means described herein and disclosed in additional strength to the Structure. the accompanying drawings, in which: A frame 23 comprises a pair of sheet Fig. 1 is a front elevation of the device metal binding strips 24 and 25 having a of my invention. longitudinal curved edge such as 26 whereby Fig. 2 is a cross sectional elevationtaken a longitudinal groove is supplied to each of on line 22 of Fig. 1 showing the device in the members 24 and 25. The'grooves in the an operative position over a warm air members 24 and 25 are adapted to receive register. the ends- 28 of rods or wires 29 which are Fig. 3 is a front elevation of a frame curved to substantially a half circle. The structure forming a detail of my invention. edge 26 of the members 24 and 25 is adapted Fig. 4 is an end elevation of the device to be clamped tightly against the body of shown in Fig- 3. said strips in order to firmly retain the ends Fig. 5 is a view taken on line 5-5 of of the curved rods or wires 29 and to retain Fig. 3. said rods in spaced parallelism as shown in 35 The device comprises a hood indicated Fig. 3. The mounting of the ends. of the generally as 8 having a shallow semi circu wires 29 upon the strips 24 and 25 may be exlar trough 9 disposed interiorly of the hood pedited by turning the ends of the wires 29 and along the rear bottom edge 10 thereof at right angles so they will readily seat in the and projecting through the end 11 of the body and the edge 26 of the members 24 and 40 hood 8 and terminating in a filling opening 25. The member 25 is adapted to seat in 12 disposed exteriorly of the hood. The hood the U-shaped groove 19 at the forward edge 8 is preferably made of sheet metal having 16 of the top wall 13 and is provided with a continuous curved top and side wall mema suitable hook member 30 which ma easily ber 13 and ends 11 and 14. The rear edge be grasped by the fingers to seat an unseat 45 10 of the curved top wall 13 is adapted to the member 25 in the U-shaped groove 19.

rest upon the floor or top portion of a hot The member 24 seats loosely in the trough 9, air register 15 while the opposite edge 16 of the resiliency of the wires 29 servmg to exthe top 13 is spaced at a distance from the ert sufficient spring action to firmly and base provided by the edge 10 and the edges yieldingly retaintlie frame in the position shown in Fig. 21. As will be readily apparent, the frame 23 is readily removable from the interior of the hood. The frame 23 is adapted to receive a lightly woven cloth or fabric 32 and to retain it in a shape conforming substantially with the frame 23. The cloth 32 is simply and expeditiously mounted upon the frame 23 by shaping it into substantially a fiat bag of a width sufficiently to receive the'strips 24 and and of a length equal to the developed length of the curved wires 29. The cloth 32 would then have one thickness disposed on each side of the wires 29 as shown in Figs. 1 and 2.

The operation of the, device is as follows:

The cloth member 32 is mounted upon the frame 23 in the manner just described and the frame thus covered is mounted interiorly of the hood by seating the member 24 in the trough 9 and passing the member 25 into the U-shaped groove 19 on the edge 16. The device. is then seated over a warm air register such as 15 and water is poured into the trough 9 most conveniently by means of the filling opening 12 disposed exteriorly of the hood. The capillary action of the cloth which may be cheese-cloth or any other suitable material, causes the entire cloth to become moistened and the heat rising from the register 15 will strike the moistened cloth 32 which will arrest dust and soot which might be driven out of the register by the action of the heat, and at the r v same time will give off some of its moisture which will be useful in humidifying the warm air which rises from the hood. By providing pockets beneath the uppermost point 21 of the hood and by providing the perforations 20 as above described, the heat will be Very readily directed against, and some of it will pass through the cloth 32, so as to insure the cleansing of the heated air rising from the register.

The cloth bag 32 may be readily removed from the frame at intervals and a clean cloth substituted for it while the original cloth is being washed.

What I claim is:

1. In a device of the class described the combination with a curved hood having an.

open bottom and front, of a trough disposed interiorly of the hood and positioned opposite the open front, a curved frame interidisposed within the trough and its opposite edge removably retained adjacent the front edge of the hood, and a porous member carried by the frame.

2. In a device of the class described the combination with a curved hood member having a front opening and perforations disposed adjacent the edge of said opening, 7

of aporous member secured along said edge of the front opening and extending in spaced relation with the curved hood portion, and means for supplying moisture to .to enclose the frame and to assume the shape of said frame, the trough being adapted to be filled with water for moistening the cloth on the frame whereby heated air rising from the register will strike the moistened porous cloth'and arrest matter in suspension in the air upon said porous cloth.

4. In a device of the class described the combination with a hood having an open bottom adapted to seat over a warm air register and having a heat discharge opening at one side and perforations in said hood adjacent the, heat discharge opening the uppermost portion of said hood forming an inverted pocket structure toward which heated air is directed from the warm air register, of a porous screen mounted in spaced relation to the interior ofthe hood and terminating adjacent the top of the heat discharge opening, and means for supplying moisture by capillary action to the screen, the perforations in the hood being adapted to discharge the air which has passed through the screen into the pocket portion of the hood.

5. In a device of the class described the combination with a warm air register, of'a deflecting hood havingan open bottom and an open side, the open bottom registering with the opening of the warm air register, a trough interiorly of the hood and disposed adjacent one side of the bottom opening of the hood, a frame oomprisin spaced parallel edges, one edge of the frame disposed at the trough and the other edge of the frame disposed at the top of the side opening of the hood, and a porous cloth covering for the frame and extending into the trough, the trough being adapted to. be filled orly of the hood and having its one edge.

with water for moistening the cloth on the frame whereby heated airrising from the register will. strike the moistened porous cloth and arrest matter in suspension in the air upon said porous cloth.

6. In a device of the class described the combination with a warm air register, of a deflecting hood having an open bottom-and an open side and having perforations in its top, the open bottom registering with the opening of the warm; air register, a trough mounted interiorly of the hood and disposed adjacent one side of the bottom opening of the hood, a frame having spaced parallel edges, one edge of the frame dis 0 posed at the trough and the other edge of the frame disposed intermediate the upper edge of thevside opening and the perforations in the top of the hood, and--a porous cloth covering for the frame and extending 10 into the trough, the trough being adapted to be filled with water for moistening the cloth on the frame whereby heated air rising from the register will strike the moistened porous cloth and arrest matter in suspension in the air upon said porous cloth.

In testimony whereof, I have hereunto subscribed my name this 11th day of April,

JOHN D. IMSANDE.
